Question

我正在尝试将鼠标悬停在图像地图上的热点上时显示一个文本框。当我将鼠标悬停在上面时，这就是我做的文字。

    <p class="ms-rteFontSize-3"><map name="FPMap0" id="FPMap0">
    <area title="Click to view" href="http://google.com" shape="rect" coords="26, 106, 133, 237"/>
    <area title="Click to view" href="http://yahoo.com" shape="rect" coords="322, 113, 414, 250"/>
    <area title="Click to view" href="http://ask.com" shape="rect" coords="402, 35, 488, 96"/>
    <area title="Click to view" href="http://naver.com" shape="rect" coords="598, 115, 682, 254"/></p>

但是，当我将鼠标悬停在上面时，我想要制作彩色的，可见的文本框。是否需要CSS？我不熟悉CSS，所以不知道在这里应用什么。

所以我将我的代码编辑到了

静止图像地图工作正常，但是当我将鼠标悬停在上方时没有任何内容。我将jQuery插件添加到SharePoint，here的示例在SharePoint页面上正常工作。

以下是如何在直接jQuery / javascript中执行您想要的操作：

Working jsFiddle here

<强> HTML：

Instructions: Mouse over computer's monitor to see hidden DIV
<div id="imagemap">
    <img src="http://img716.imageshack.us/img716/8287/3ylp.jpg" width="275" height="207" usemap="#Map" border="0" />
    <map name="Map">
        <area shape="poly" coords="105,26,107,126,257,140,256,27" href="#" id="CUST_1" name="CUST:1" />
        <area shape="poly" coords="10,21,14,178,71,184,69,19" href="#" id="CUST_2" name="CUST:2" />
        <area shape="poly" coords="113,145,94,172,241,192,251,164,250,164" href="#" id="CUST_3" name="CUST:3" />
    </map>
    <p>
        <div id="myDiv">This DIV hidden unless hover over the computer's monitor</div>
    </p>
</div>
<!-- Yellow DIV ID numbers overlaid on top of computer components -->
<div id="num_cust1">1</div>
<div id="num_cust2">2</div>
<div id="num_cust3">3</div>

<强>的javascript / jQuery的：

function hovIn() {
    var areaID = $(this).attr('id');
    //alert('['+areaID+']');
    if (areaID == 'CUST_1') {
        $('#myDiv').show();
    }
}

function hovOut() {
    $('#myDiv').hide();
}

$('map area').hover(hovIn, hovOut);

<强> CSS：

#num_cust1 {
    padding: 10px;
    background-color:yellow;
    position:absolute;
    top:60px;
    left:180px;
}
#num_cust2 {
    padding: 10px;
    background-color:yellow;
    position:absolute;
    top:60px;
    left:40px;
}
#num_cust3 {
    padding: 10px;
    background-color:yellow;
    position:absolute;
    top:160px;
    left:180px;
}
#myDiv {
    display:none;
    width:50%;
    height:50px;
    padding: 10px;
    background-color:skyblue;
}

Answer 2

您是否愿意使用jQuery？

如果有，您是否听说过ImageMapster plugin？

有关演示的详情，请参阅此链接：http://www.outsharked.com/imagemapster/default.aspx?demos.html

由于ImageMapster是一个jQuery插件，你需要在页面的head标签中包含以下几行：

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script src="//www.outsharked.com/scripts/jquery.imagemapster.js"></script>

第一行加载jQuery库，下一行加载ImageMapster插件。

之后，只是使图像映射有效的代码。

请参阅上面的演示，了解您可以做些什么。
